Premature senescence of rice is caused by the wilting of stems and leaves and the premature aging of the leaves during the period from heading to maturity, resulting in the lack of grain and the reduction of yield in the valley. The premature aging of rice in the middle and late stages occurs every year. The general situation is mainly due to the high temperature in the early stage. The farmers' friends have cooled down the water and drained the water, resulting in no loss of fertilizer after the loss of fertilizer. On the other hand, the lack of certain elements in the middle and late stages of rice, shallow ploughing, low fertility, can not meet the demand for nutrients in crops, etc. are also prone to premature aging. Control technology: We must carry out nutritional supplements when we find that the rice has premature aging in the field. Generally take the application of quick-acting fertilizer, but this time can not chase more, to avoid the emergence of late greed and lodging, you can use 4-5 pieces of urea and 5 kg of potassium chloride. In addition, combined with pest control, it can be applied through the application of trace element fertilizer in foliar application. It can choose high potassium fertilizer, excellent potassium, and application of pesticides to ensure a certain green leaf area in the late rice, and improve the photosynthetic capacity of the leaves. Photosynthetic efficiency, promote rice filling, increase seed setting rate and 1000-grain weight, so as to achieve the purpose of increasing grain, gaining weight and improving quality.
